PTFE Washer /PTFE Valve Seat/PTFE Gasket/PTFE Ring/PTFE Seal (O Ring PTFE Gasket PTFE washer PTFE ball)

1. High surface finishing 2. Precision in dimension control:±0.005mm 3. Full Inspection 4. Short Lead Time PTFE Performance: Teflon® is renowned for its temperature resistance and slick, non-stick qualities. As an industrial material, Teflon® has exceptional chemical resistance, high and low temperature durability, low coefficient of friction and superb insulating qualities. It lacks toughness for abrasive applications, however, and is not readily fastened together using adhesives unless the surface is ôetched" to accept the bonding agent. Teflon's® properties can be improved with the addition of fillers such as glass fiber and carbon.
